-Subject: [PATCH] mtd: rawnand: brcmnand: disable WP on BCM4908
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-BCM4908 contains NAND controller version 0x0701 (v7.1). It means that
-NAND_WP should be available.
-
-For some reason setting #WP on doesn't result in clearing NAND_STATUS_WP
-status bit:
-[    1.077857] bcm63138_nand ff801800.nand: timeout on status poll (expected c0000040 got c00000c0)
-[    1.086832] bcm63138_nand ff801800.nand: nand #WP expected on
-
-For now try working without touching #WP.
